A system including a vapor chamber including a liquid. The vapor chamber is coupled with a die. The vapor chamber is attached to a plurality of micro pipes (MPs). When heat is generated by the die, the liquid is vaporized in the vapor chamber generating vapor. The vapor flows through the MPs to condensation ends of the MPs.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system, comprising: a die; a vapor chamber coupled with the die, the vapor chamber including a working liquid; and a plurality of micro pipes (MPs) attached to the vapor chamber at vapor chamber connection points, wherein heat generated by the die causes the working liquid in the vapor chamber to vaporize generating vapor, the vapor flowing from the vapor chamber though the MPs toward condensation ends of the MPs.
2. The system of claim 1 , wherein each of the plurality of MPs has a small cross section.
3. The system of claim 2 , wherein the cross section is up to 1 mm.
4. The system of claim 2 , wherein each of the MPs comprises a central insulated section made of flexible material, the central insulated section having an internal surface structured to provide capillary action.
5. The system of claim 4 , wherein the vapor is condensed into the working liquid at the condensation end, and wherein the working liquid is returned to the vapor chamber by the capillary action.
6. The system of claim 3 , wherein the condensation end is metallic.
7. The system of claim 6 , wherein the condensation end is attached to a heat exchanger.
8. The system of claim 6 , wherein airflow is applied to the condensation end to provide condensation of the vapor.
9. An apparatus, comprising: a vapor chamber having a liquid and a cavity region; and multiple tubes connected to the vapor chamber at connection points on the vapor chamber, each of the multiple tubes having a vapor region and a liquid region, wherein when heat is transferred to the vapor chamber the liquid is vaporized into vapor sending the vapor into the cavity region and out into the multiple tubes at the connection points, the vapor flowing through each of the multiple tubes in the vapor region toward a condensation end of the tube where the vapor is condensed into liquid, the liquid returned in the liquid region back to the vapor chamber by capillary force.
10. The system of claim 9 , wherein each of multiple tubes is a heat pipe having a central insulated section made of flexible material, the central insulated section having a capillary wicking internal surface.
11. The system of claim 10 , wherein each of the multiple tubes has a cross section of length up to 1 millimeter (mm).
12. The system of claim 9 , wherein the tube is sealed at the condensation end and connected to the connection point at an opposite end.
13. The system of claim 12 , wherein the condensation end is metallic.
14. The system of claim 13 , wherein the condensation end is attached to a heat exchanger.
15. The system of claim 13 , wherein the condenation end serves as a heat exchanger by directing airflow toward the condensation end.
16. A method, comprising: attaching a vapor chamber to a die, the vapor chamber including a cavity region, a liquid and multiple connection points; and connecting a tube to each of the multiple connection points at an open end of the tube such that when heat is absorbed from the die by the vapor chamber, the liquid is vaporized into vapor, the vapor flowing into the cavity region and out to the tubes at the connection points toward a closed end of the tube.
17. The method of claim 16 , wherein the closed end of the tube is metallic.
18. The method of claim 17 , further comprising condensing the vapor into liquid at the closed end of the tube.
19. The method of claim 18 , wherein the tube comprises a central insulated section made of flexible material, the central insulated section having a capillary wicking internal surface, wherein the liquid is returned to the vapor chamber by capillary force.
20. The method of claim 18 , wherein the closed end of the tube is atached to a heat exchanger.
21. The method of claim 18 , wherein the condensing the vapor comprises directing airflow to the closed end of the tube.
22. The method of claim 16 , wherein the tube has a cross section of up to 1 millimeter.
